Health monitoring assist system

Abstract

A health monitoring assist system includes: a unit that acquires time-series data of an activity index that indicates an amount of an activity conducted by a subject; a unit that acquires time-series data of a biological index measured from, and relating to health of, the subject; an estimation unit that estimates an amount of time lag between a change in the activity index and a resultant change appearing in the biological index based on a result of comparison between the time-series data of the activity index and the time-series data of the biological index; and a unit that provides the subject with assist information that indicates that an effect caused by the activity of the subject is apparent in a value of the biological index after the amount of time lag from a time point when the activity was conducted, based on an estimation result of the estimation unit.

         2 . The health monitoring assist system according to  claim 1 , wherein the assist information includes information indicative of the amount of time lag. 
     
     
         3 . The health monitoring assist system according to  claim 1 , wherein the assist information includes a graph plotting the time-series data of the activity index and shifted by the amount of time lag, and a graph plotting the time-series data of the biological index. 
     
     
         4 . The health monitoring assist system according to  claim 1 , wherein the assist information includes information indicating a period, in a graph plotting the time-series data of the biological index, in which a positive change caused by an increase in the activity index is apparent in the biological index. 
     
     
         5 . The health monitoring assist system according to  claim 1 , wherein the assist information includes information indicating a period, in a graph plotting the time-series data of the biological index, in which a negative change caused by a decrease in the activity index is apparent in the biological index. 
     
     
         6 . The health monitoring assist system according to  claim 1 , wherein the time lag estimation unit evaluates intensity of a causal correlation between the time-series data of the activity index and the time-series data of the biological index with respect to a plurality of amounts of time lag, and selects an amount of time lag with which the intensity of a correlation is highest as the amount of time lag between the change in the activity index and the resultant change appearing in the biological index. 
     
     
         7 . The health monitoring assist system according to  claim 6 , wherein the time lag estimation unit evaluates the intensity of the causal correlation between the time-series data of the activity index and the time-series data of the biological index with use of transfer entropy. 
     
     
         8 . The health monitoring assist system according to  claim 1 , wherein the information presentation unit presents the assist information to a terminal owned by the subject by wired or wireless connection. 
     
     
         9 . A terminal capable of communicating with the health monitoring assist system according to  claim 8  by wired or wireless connection, comprising:
 a request unit that transmits a request for assist information to the health monitoring assist system together with information for identifying the subject who owns the terminal; and 
 a display unit that displays the assist information received from the health monitoring assist system. 
 
     
     
         10 . The terminal according to  claim 9 , further comprising a data transmission unit that transmits data of an activity index of an activity conducted by the subject and/or data of a biological index measured from the subject to the health monitoring assist system. 
     
     
         11 . The terminal according to  claim 9 , further comprising a measurement unit that measures the activity index. 
     
     
         12 . The terminal according to  claim 9 , further comprising a measurement unit that measures the biological index. 
     
     
         13 . A non-transitory computer readable storage medium storing a program that makes a computer function as:
 an activity index data acquisition unit that acquires time-series data of an activity index indicative of an amount of an activity conducted by a subject;   a biological index data acquisition unit that acquires time-series data of a biological index measured from, and relating to health of, the subject;   a time lag estimation unit that estimates an amount of time lag between a change in the activity index and a resultant change appearing in the biological index based on a result of comparison between the time-series data of the activity index and the time-series data of the biological index; and   an information presentation unit that provides the subject with assist information that indicates that an effect caused by the activity of the subject is apparent in a value of the biological index after the amount of time lag from a time point when the activity was conducted, based on an estimation result of the time lag estimation unit.   
     
     
         14 . A non-transitory computer readable storage medium storing a program that makes a terminal capable of communicating with the health monitoring assist system according to  claim 8  by wired or wireless connection function as:
 a request unit that transmits a request for assist information to the health monitoring assist system together with information for identifying the subject who owns the terminal; and 
 a display unit that displays the assist information received from the health monitoring assist system.
